Liquid markup language

Liquid is an open-source template language created by Shopify and written in Ruby. It is the backbone of Shopify themes and is used to load dynamic content on storefronts.

Liquid has been in production use since June 2006 and is now used by many other hosted web applications.

Liquid was written with very specific requirements:

• It has to have simple markup.

• It needs to be secure.

• It has to be stateless. Compile and render steps have to be separate so that the expensive parsing and compiling can be done once and later on you can just render it passing in a hash with local variables and objects.

The liquid code looks like the following:

<ul id="products">
  {% for product in products %}
    <li>
      <h2>{{ product.name }}</h2>
      Only {{ product.price | price }}

      {{ product.description | prettyprint | paragraph }}
    </li>
  {% endfor %}
</ul>
